Well, there are a number of possible reasons - like for example if the cutting object does not intersect the thing you're trying to trim it won't produce any result. Or if you have a curve that intersects a surface it must cut the surface into 2 complete pieces you can't trim with a cutting curve that looks like this for example:



It's pretty much impossible for me to know what particular problem you might be running into without actually seeing the model file that you're working with.
